Abstract
A continuous steel strip consisting especially of austenitic or martensitic steel, with at least one weld seam running crosswise to the longitudinal extension of the steel strip, for twin presses. The steel strip includes at least one first surface layer which extends essentially across the entire steel strip and which has a different composition to an intermediate layer located between said first surface and a second surface facing the first. The intermediate layer extends essentially across the entire steel strip. The first surface layer consists of the steel of the steel strip and has regularly positioned heat-influenced areas, e.g., zones, situated next to or overlapping each other and/or fusion penetration areas, e.g., zones.
